Specification of Letters atent.

Patented Oct. 3, 1905.

Application led February ll, 1904. Serial No. 193,080.

Be it known that I, HOBERT J. HURD, acitizen of the United States,`and aresident of Bridgeportjn the county of Fairlield and State ofConnecticut, haveinvented certain new and useful Improvements infad-Printing Machines, of which the following is a specification.

My inventionrelates to improvements in machines for printing gun-wads onboth sides; and it consists in certain details of construction to bemore fully set forth in the following specification, and such featuresthat are believed to be new and novel will be partielllarly set forth inthe claims.

To enable others to understand myinvention, reference is had to theaccompanying drawings, in which- Figure 1 represents a side elevation ofthe machine and broken view of its standard and wad-feeding mechanism.Fig. 2 is an upper plan view of the machine. Fig. 3 is an enlargedcentral sectional view of the gear, having a cam on its vertical faceadapted to actuatc the vertically-operating slides pertaining to theprinting' mechanism, sectional View of said slides, enlarged View of theupright, and sectional View of the wad-magazine through line e of Fig.2. Fig. 4 is an enlarged broken sectional View of the support on whichthe cam-gear actuating the slide of the printing mechanism rotatesthrough line 7) of Fig. 3, also upper plan View of the wad -feedingmechanism. Fig. 5 is an enlarged detail View of the distributing andinking rolls, broken view of the inlzing-pads, broken view of thetype-carriers. and sectional view of the inkfountain. Fig. 6 is anenlarged upper plan view of one of the distributing-rolls and one of theinlring-rolls and frame for same. Fig. 7 is an upper plan view of thewad-feeder and broken view of its supporting-bracket, showing the methodof feeding the wads. Fig. 8 is a similar view showing wads of smallerdiameter being fed.

Its construction and operation are as follows:

l is the standard of the machine; 2, the bed.

3 is the driving-shaft, carrying the handwheel 4, tight pulley 5, andloose pulley 6. The shaft 3 is journaled in the bracket 7, secured tothc upright 8. 9 is a pinion on said sha ft registering with the largegear 10, Figs. This gear is rotatably mounted on 1 and 3.

the hollow journal 8"L of the frame 8 and is provided with thecam-groove 11 on its vertical face to receive the rolls 12 and 13, whichrolls are mounted on the head of the screws 14 and 15, secured to thevertically-operating slides 16 and 17. 18 and 19 are housings projectingfrom these slides, which slides carry the adjustable shells 2O and 21,and their threaded ends carry the nuts 22 to adjust the verticalposition of these shells. 23 and 24 are typecarriers mounted in saidshells, the reduced portions 23a and 24 passing through the ends of saidshells. 25 and 26 are adjusting-nuts mounted on said threaded portionsfor the purpose of adjusting a spring placed between a shoulderedportion of the type-carrier and the ends of the shells. One of saidsprings 27 is shown at Fig. 3. These springs permit the type-carriers toreact or give back slightly under the printing blow.

28 and 29 are type mounted in the inner ends of the type-carriers.

The worm or screw wad-feeder consists of the body portion 30, having thecoarse thread 30u. This feeder is rotatably mounted in the adjustablebox 31 and is intermittently rotated through the medium of thedrivingshaft 3 as follows: 32 is a plate, Figs. 1 and 2, mounted on theend of said shaft, and it carries the screw 33. 34 is a connecting-rodhaving one end pivotally supported on this screw and its other end onthe screw 35 ofthe arm 36. The hub portion 36n of this arm is journaledon the screw 37, projecting from frame or upright 8. 38 is a pawlpivotally supported on the arm 36, adapted to engage with the notchedplate 39 of the gear 40, rotatably mounted on the stud or screw 37. Thisgear meshes with the pinion 41 of the wadfeeder to eifect anintermittent rotary movement of said feeder through the medium of themechanism just described.

42' and 43 are ink-fountains having a longitudinal adjustment (see alsoFig. 5) through the medium of the elongated holes 44 and 45, embracingthe side clamping-screws 46 and 47. 48 and 49 are fountain-rollsjournaled on the pins 50 and 51 in the end of said inl(- fountains.

52 and 53 are ink-Scrapers adapted to be' adjusted to and from thefountain-rolls by means of the adjusting-screws 54 and 55 (see alsoFigs. 1 and 2) to remove surplus ink from the surface of said rolls.These rolls vof are iluermittently rotated as follows: 56 is i l andlower type.

cam-plate mounted on the shaft 8 and has on its outer periphery theprojection 56" to engage with the roll 57', mounted on the lower end ofthe vertical link 59 and 60 are arms carrying` the pawls 61 and 62,adapted to engage with the ratchet-wheels 63 and 64,

secured to the pins and 51 of the Vfountain-rolls. One end of thel saidarms is journaled on the said pins and the other end on the screws 65and 66 of the link 58.

67 and 68 are the inking-pads secured to the frame or upright 8 and arevertically adjustable thereon.

69, Fig. 1, is a reciprocating slide adapted to operate through themedium of the level' 71, whose upper end carries the link 72, connectedto said slide. The lower end of this lever is journaled on the pin 73,projecting from the bed of the machine, while intermediate of the endsof this lever is the roll 74, adapted to engage with the cam-groove inthe inner vertical face of the cam-plate 56.

Referring to Fig. 76 is a stud projecting from the slide 69, and 77 and78 are levers pivotally supported on this stud. 79 and 80 are Vframespivotally supported on the outer ends of these levers, and 81 and 82 arethe ink-distributing rolls, and 83 and 84 are the inking-rolls journaledin said frames. 85 is a spring-clip eng'aging the inner ends of saidlevers, so as to apply an outward pressure to said rolls. 86 is anadjusting-screw to regulate such pressure. The reciprocating movement ofthe slide will bring the distributingrolls against or in close proximityto the rotata ble fountain-rolls on each backward movement of the slide,and the amount of ink taken up by these distributing-rolls is determinedby the closeness of this proximity and the amount of ink carried by thefountainrolls. The Yforward movement of the slide will cause the rolls81 and 82 to distribute the ink evenly onto the surface of theinkingpads, so that the inking-rolls 83 and 84 will take up thenecessary amount of ink for the type as said rolls pass over the pads.

l 87, Figs. 1, 2, 3, and 4, is the gravity-feeding wad-magazine, whichis filled with the unprinted wads 88. The magazine overlies an opening'in the cap 89 of the box 31, with its foot secured to the side of saidbox. The wads drop Yfrom the magazine one at a time onto the cylindricalbody portion of said feeder and between the threads, and they are keptfrom rotating' or turning' with the feeder by reason of the engagementof their edges with ythe cham'xel-way 89, formed on the under surfaceofthe caps 89. As fast as one wad passes from under the magazine anothertakes its place and is in turn fed on toward the type in one cominuoussuccession.

9i), Figs. 3 and 4, is an interchangeable dieplate located at theforward end of the wadfeeder, havingl the hole 91 to admit the upperThis plate is also provided with the channel-way 92 to guide the wadscentrally with respect to the type. As soon as a wad is printed it ispushed out of the range of the type by the next incoming wad deliveredvfrom the feeder'. The printed wads are forced along the block 93,extending through the hollow journal 8", and are delivered at its end,as shown at Fig. 4. This block has the overlying caps 94, which capsalso have the channel-way 95.

The great advantage of the worm or screw Vfeeder over a dial-feederrotating in a horizontal plane, where the wads are fed into holescircumfcrentially arranged in said dial, is the less number of partsrequired, more accurate delivery of the wads to the type, and thenecessity avoided of changing' the size of the worm or screw 'feeder fordiiierent sizes oli' wads, which is necessary where a dial-feed is used.

The pitch of the screw or space between the threads, Fig. 7, is made toreceive wads of the greatest diameter required. The central portionbetween the threads will of course be central with the center of themagazine, so that when a large-sized wad is deposited on the feeder itwill about lill the space between the threads 30, The main determiningfactor, however, in securing correct feeding is the engagement ofl theright-hand face of the threads with the edge of the wads, for it is thisface that engages with the edges of the wads to move them forward, andtherefore the location of the edge of the wads with this `face is veryimportant.

The placing of the wads between the type so that their center(represented by the line c) shall lie central with the type isdetermined` by the extreme end 30" of the thread. In other words, thedistance between the extreme end 30" of the thread and the center of thetype is equal to one-half the diameter of the wad being fed, so thatwhen the wad is between the tyge the thread portion of the screw-feederexerts no further pushing inlinence on the wad, and when the wad solocated is printed another wad is fed along', as before mentioned, topush the printed wad away from the type and take its place.

All that is necessary in printing wads of smaller diameter is to changethe die-plate 90 for one having a channel-way which equals the diameterof the wad to be printed and move the box 31, in which the screw-feederis journaled, forward, as follows: 96, Fig. 8, is a bracket integralwith the upright 8 and is provided with the elongated holes 97 for thescrews 98, which screws are attached to the box 31. WThen, therefore,smaller wads are printed, this box is loosened and moved forward againstthe die-plate. Then a small wad drops onto the body portion of thescrewfeeder, it will lie midway of the threads; but as it cannot rotatewith the feeder it will re- IOC) IIO

main stationary for an instant until the thread has caught up andengaged its edge to push it forward.

\Vhatever position the box 3l occupies, the end 30" of the thread of thescrew-feeder must always stand from the center of the type a distanceequal to one-half the diameter of the wads that are being printed. Thispo'- sition can be accurately and quickly determined by means of thelines or scale /L on the bracket and box, or, Figs. 3 and 4, thedistance from the edge c' of each die plate or block to the center ofits type-hole 91 equals one-half of the diameter of the wad intended tobe used with said die-plate. I

To counteract the wear of the cam-groove il and the rolls of the slideswhich operate therein, I employ the adjustingscrews 99 and 100, Fig. 3,whose points are adapted to engage with the enlarged portion 8" of thehollow journal S" when the type engages with a wad. This makes apositive limitingpoint for the inward travel of the type.

Another great advantage of the screwfeeder over the dial-feed lies inthe fact that if through the carelessness of the operator the magazineshould become empty there will always be a wad between the type toprevent the type-faces coming in direct contact with each other.

The machine above described is not only cheap and simple of constructionand containing but few parts, but it is absolutely correct and accuratein its operation and is capable of printing more wads in a given lengthof time than can be done by a machine using` a dial-feed.
